Device for fixing hard disk

ABSTRACT

A device with shock-absorbing qualities for fixing a hard disk in place on a chassis includes two brackets, a plurality of shock-absorbing cushions, and a plurality of first fasteners is described. The brackets located at opposite sides of a hard disk and the side surface of the bracket define a plurality of circular through holes with notches or cutaways continuing to the outer edge of the side surface. The cushions can be locked in the circular through holes after being introduced through the notches whilst sleeving the first fasteners. Two support portions are bent from ends of each bracket to support the hard disk in place.

FIELD

The subject matter herein generally relates to devices for fixing hard disk.

BACKGROUND

Hard disks are a common storage medium. In many cases, hard disks are fixed to brackets. A bracket is generally U-shaped and defines a number of circular through holes at sides of the bracket to connect the hard disk to a chassis of a computer. A cushion is generally positioned at the circular through hole. A diameter of the cushion is larger than a diameter of the circular through hole, which makes disassembly and assembly inconvenient.

Therefore, there is room for improvement within the art.

FIG. 1 and FIG. 2 illustrate a device 100 according to a first embodiment of the present application. The device 100 fixes a hard disk 300 to a chassis body 200. The device 100 includes a plurality of brackets 10, a plurality of cushions 20, and a plurality of first fasteners 30.

In the embodiment, the device 100 includes four cushions 20 and four first fasteners 30. The two brackets 10 are fixed to the chassis body 200 at intervals and are positioned on opposite sides of the hard disk 300. Each of the brackets 10 includes a plurality of circular through holes 13 and a plurality of notches 14. Two ends of each of the notches 14 extend to one of the circular through holes 13 and an edge of the bracket 10. In the embodiment, each of the brackets 10 defines two circular through holes 13 and two notches 14. The notch 14 is located on a side of the circular through hole 13 along an extension direction of the bracket 10. In another embodiment, the notch 14 is located below the circular through hole 13, the notch 14 still extends to the circular through hole 13.

An annular locking slot 21 is provided on a circumferential surface of each of the cushions 20. The annular locking slot 21 is configured to lock the bracket 10. The notch 14 extends from an edge of the bracket 10 to the circular through hole 13, allowing a sidewall of the annular locking slot 21 to pass through the notch 14 and into the circular through hole 13 to lock the bracket 10 in the annular locking slot 21. In an embodiment, the bracket 10 is locked in the annular locking slot 21 in a transitional fit or a tight fit. The cushion 20 is elastically deformed so that the sidewall of the annular locking slot 21 is clamped to the bracket 10.

A first end of the first fastener 30 abuts against a side of the cushion 20, and another end of the first fastener 30 passes through the cushion 20 and the circular through hole 13 to connect to the hard disk 300. In the embodiment, the first fastener 30 includes a shaft body 33 and a protrusion 31 protruding from an end of the shaft body 33. A surface of the protrusion 31 adjacent to the shaft body 33 abuts the cushion 20. An end of the shaft body 33 away from the protrusion 33 has an external thread. The hard disk 300 is provided with a plurality of threaded holes 36. The end of the shaft body 33 away from the protrusion 33 is screwed in the threaded hole 36 of the hard disk 300.

The bracket 10 has an elongated strip shape. The bracket 10 includes a bottom surface 11 and a side surface 12 perpendicular to the bottom surface 11. The circular through hole 13 and the notch 14 penetrate the bracket 10 from the side surface 12. The notch 14 further penetrates the bottom surface 11, so that the cushion 20 can move from the notch 14 to the circular through hole 13 and be locked in circular through hole 13. Two support portions 15 are vertically bent from two opposite ends of the bracket 10. The two support portions 15 intersect two short sides of the side faces 12. In a direction parallel to the short side of the side surface 12, two support portions 15 extend below the bottom surface 11 and then vertically bend toward each other to form two abutting portions 17.

The device 100 further includes a number of second fasteners 40. Each of the second fasteners 40 passes through one of the abutting portions 17 and is coupled to the chassis body 200 to fix the bracket 10 to the chassis body 200. A top surface of the bracket 10 opposite to the bottom surface 11 is not in contact with the chassis body 200. Thus, the bracket 10 can be used to mount the hard disk 300 at different heights. In the embodiment, the two abutting portions 17 of the bracket 10 are located between the two supporting portions 15. In another embodiment, the two support portions 15 of the bracket 10 are located between the two abutting portions 17.

The two support portions 15 are provided on sides of the bracket 10 facing the hard disk 300. A distance between the two support portions 15 of the bracket 10 is greater than a length of the hard disk 300 to allow installation space for the second fastener 40. In another embodiment, the two support portions 15 of the bracket 10 are provided on sides of the bracket 10 away from the hard disk 300. The distance between the two support portions 15 of the bracket 10 can be bigger or shorter or equal to the length of the hard disk 300.

In an embodiment, the hard disk fixture 100 further includes a plurality of buffering members (now shown). The buffering members are provided between the abutting portion 17 and the chassis body 200. The second fastener 40 sequentially passes through the abutting portion 17 and the buffering member to connect to the chassis body 200. The cushion 20 and the buffering member are made of a shockproof or shock-absorbing material, for example, rubber.

When installing the hard disk 300 to the chassis body 200, the annular locking slot 21 is aligned with the notch 14, and the cushion 20 passes through the notch 14 into the circular through hole 13. The sidewall of the annular locking slot 21 is clamped to the bracket 10. The circular through hole 13 is aligned with the threaded hole 36 of the hard disk 300. The shaft body 33 passes through the cushion 20 and the circular through hole 13 and connects to the hard disk 300. Opposite surfaces of the cushion 20 abut against the protrusion 31 and the hard disk 300. The brackets 10 are positioned at opposite sides of the hard disk 300 and connected to the opposite sides of the hard disk 300. The bracket 10 is positioned on the chassis body 200 and the abutting portion 17 touches the chassis body 200. The second fastener 40 passes though the abutting portion 17 to be coupled to the chassis body 200 and the bracket 10 fix the hard disk 300 to the chassis body 200.
